Quickfixes
Create .img on Linux CLI
It's quite simple to create an image of a disk, for example an SD card, therefore use the following command:
dd if=/path/to/device of=image.img
The /path/to/device
can be found out with:
lsblk
For example it can be /dev/sda
.
Remind that using this method will include also empty parts. An image of a 32 GB SD card will later have a size of 32 GB although for example 16 GB are unused.

sudo service sddm stop
And without re-login:
kquitapp5 plasmashell && kstart5 plasmashell
